Product Description
- The SMC HRSH series cooling and temperature control unit is used for cooling and temperature control of circulating media in industrial production and process plants.
- It is suitable for applications with fluctuating heat loads where a controlled medium temperature is required. The unit is used to dissipate process heat and to maintain the temperature of circulating media in machinery and plant.
- Via the available communication interfaces, the cooling and temperature control unit can be integrated into higher-level control systems and used in automated production processes.
- The SMC HRSH series cooling and temperature control unit is an air-cooled industrial cooler designed to regulate the temperature of circulating media in industrial plants.
- The unit features triple inverter technology comprising a DC inverter compressor, a DC inverter fan and an electronic expansion valve. These components are used to regulate the cooling capacity in accordance with the prevailing operating conditions.
- Temperature control is carried out by a PID controller, which regulates the temperature of the circulating medium based on the setpoint.
- In addition, the cooling and temperature control unit features a heating function that operates without a separate electric heating element.
- RS-232C and RS-485 serial interfaces, as well as digital inputs and outputs, are available for integration into higher-level control systems.
